CME Group Inc.'s daily trading volume marked an all-time record in August, according to the derivatives exchange operator, while rival IntercontinentalExchange Inc. also reported a sharp jump in activity.

Kicked off with Standard & Poor's unprecedented downgrade of the U.S. credit rating, August was a highly volatile month for markets of all varieties.
